What is Zero Trust?
Zero Trust is a security framework that implicitly trusts any device, user, network or service, and requires constant confirmation of authentication and authorization required for accessing corporate information. This Zero Trust model assumes that an incident is likely to occur and could have already occurred, so it imposes restrictions on access and provides alerts for suspicious activities. Zero Trust is a framework to secure corporate data for the digital age of today. It was designed to meet the challenges that technology brings to today’s company, which includes threats to insiders as well as secure remote access ransomware , and much more.
Zero Trust security has three principal ideas:
1. Continuous monitoring
In the Zero Trust model, we believe that there are attackers within and outside our organization boundary, so no one are automatically trusted. Zero Trust verifies every single user’s access.
2. Most privilege
Although users frequently access corporate data in the course of their task The principle of least privilege guarantees that they are granted only the information they require to carry out their job efficiently. Based on “a need to be aware” basis. This limits each user’s exposure to sensitive information. In the event of a security breach, Zero Trust limits the extent of the breach and allows security teams to react and mitigate the threat.
3. Automation
Continuous monitoring and lowest privilege access are not possible without full automation of these procedures. Zero Trust database access embraces the full implementation of security automation to ensure that users have the least privilege access. We also continuously monitor and validate every single data connection made from every single user both within and outside of the company.
What is the reason ZTNA not sufficient to be used for SaaS Data Security?
The most commonly used usage case for this Zero Trust security model is secure remote access, or Zero Trust Network Access (ZTNA). This product type eliminates the requirement for a VPN that is not a standard feature and focuses on its Zero Trust principles to verify the remotely accessible network by micro-segmentation of the device and network, as well as access control.
ZTNA solutions offer an impressive and extensive micro-segmentation as well as access control by analyzing identity as well as network and device metadata, like your IP address, OS versions, and the roles of users. ZTNA can solve a variety of significant threats, including attack on accounts (examples of access that is allowed to unknown devices and networks). When ZTNA solutions allow access to the network, the user can connect to the permitted applications, without any micro-segmentation as to the “kind” information in the applications is able to be accessed, altered and shared. In particular, in the case of SaaS applications, users can access and alter SaaS data, without having to worry about any additional granularity in access controls through ZTNA. ZTNA solution.
In the case of an employee, for instance, one who leaves a company can steal and scrape substantial amount of sensitive data from the company before leaving the company just because the identity of their device and network metadata are accepted by ZTNA. ZTNA solution. There isn’t any context surrounding data exfiltration or the type of data is being extracted. So, businesses that are implementing ZTNA solutions are still vulnerable to a variety of day-to-day threats:
Employees who resign for leaking company information
Inadvertent sharing of company data with personal accounts
Internal exposure and consumption of sensitive information
3rd party partners exposed to corporate data for a lifetime
Data can be shared with anyone who can access the link

Why can’t we Trust Data Access?
Zero Trust Data Access (ZTDA) utilizes the concept of least privilege along with micro segmentation as a concept and applies it to Software as a Service (SaaS) applications, which are among the most important sources of data for any enterprise striving to be aligned with an Zero Trust model.
ZTDA is a new guideline principle that allows for the granularity to ensure that trust implicitly isn’t given to any user within or outside of the company, over and above the layer of identity or deep rooted in the SaaS application layer. This allows more specific security rules that can be applied to all end users and other entities which are external and internal in the entire range of SaaS applications.
ZTDA secures the vital resources that propel the modern day business forward.
When ZTNA micro segments are focused on networks, identities, as well as the devices they use, ZTDA micro segments on users, third partners, identity providers, Group memberships, HR employee status the type of file, file place of origin, PII detection, malware detection, and more.
ZTDA utilizes to the 3 Zero Trust principles as follows:
1. Continuous monitoring
ZTDA platforms are connected to all external and internal user activities, SaaS assets metadata, and data enrichments that are derived from many interconnected integrations, including IDP, EDR, and HR platforms. All these information points are merged to provide deep micro-segments across different levels, including users groups, assets and domains, employment status, and many more. ZTDA platforms maintain a live list of your SaaS ecosystem’s metadata, without the need to replicate and keep SaaS hosting data.
2. The least privilege
Based on the unification of catalog and the data enhancements ZTDA platforms are constantly revoking access to data for users from both sides to ensure the lowest privilege model in a large scale. Users are able to ask for access, or even share exactly the same data repeatedly to ensure that business enablement remains in the same way. As time passes, companies that adopt ZTDA platforms can significantly decrease their vulnerability, the quantity of individuals who have access to sensitive information and the scope of any breach that could occur.
3. Automation
ZTDA platforms can automate workflows that are powered by a complete micro-segmentation for users and collaborators, assets groups, and much more. These workflows aren’t necessarily based on opinion or hardcoding, however they are highly flexible and adaptable to trigger in response to any user or any other anomalous event that is identified. ZTDA platforms have a vast range of remediation options, which can be triggered on demand as well as fully automatized.
How can you implement Zero Trust on the data layer?
There are no two security programs or teams alike. So Here are the basic steps to implement the Zero Trust data Access model:
Visualize to understand the entire team of collaborators, users as well as groups, assets and the risks.
Reduce – address identified threats to enhance your security position.
Automate workflows to avoid situations with high risk.
Adjust your security requirements based on changes in your business.
